with out even looking it up, trip can be a voyage (going on a vacation trip) or a mis-step (my daughter tripped, and fell, and broke her ankle) for real! and it can also be 'moving brisk, or spritely'--trippingly not to mention all the drug realated 'trips' one can take.

to "trip the lights fantastic" is to walk (lightheartedly, spritely') along broadway-- (NY 'great white way' before neon lights made it multicolor!)--
